- What was the average number of fiction books borrowed by each visitor that Wednesday? Give your answer to the nearest whole number.
(a)
Total number of visitors
= 54 + 26 + 38 + 16 + 59
= 193
(b)
Total number of fiction books borrowed
= 2 x 54 + 3 x 26 + 4 x 38 + 5 x 16 + 6 x 59
= 108 + 78 + 152 + 80 + 354
= 772
Average number of fiction books borrowed
= 772 ÷ 193
= 4
≈ 4
Answer(s): (a) 193; (b) 4
